Havenstar

The Eight Stabilities are islands of order surrounded by lethal chaos – and the order is being swallowed by the unstable. The religious leaders of Chantry try to maintain the Stabilities by ordering the necessity of a once in a lifetime pilgrimage across the chaos. And in that ever-changing world, the most important person is a mapmaker who can make a chart of secure pilgrimage routes...

Keris Kaylen is a mapmaker's daughter. When her father is murdered and a mountain disappears, Keris is betrayed by her brother. Forced to flee into the Unstable, she finds her safety is in the hands of a man bonded to the Lord Carasma, the Unmaker... and her ordered life is turned upside-down. Her survival will depend on a map and a place called Havenstar – but she can't reproduce the map, and Havenstar may not even exist...
